A former Stroudsburg Area School District music teacher charged with sexual contact with a teenage student in his office was sent to Monroe County Prison on Wednesday, according to court records.

Brandon W. Flatley, 39, of Stroudsburg, was arraigned on criminal charges and sent to prison under $75,000 bail, according to court records.

Flatley is charged with three counts each of intercourse/sexual contact with a student, corruption of minors, unlawful contact with a minor and criminal use of a communication facility.

Stroud Area Regional police said Flatley was fired last month after authorities said he had sexual contact with a 16-year-old student at the intermediate school and at a private home. Police said Flatley also sent the girl an average of 142 messages a day over a 20-month period.

Police said Flatley met the student in 2007 during his first year as a full-time, fourth-grade music teacher in the district.

Authorities said when the student was 16, Flatley sent her messages with sexual content. Police said Flatley also had sexual contact with the girl during school hours at his office and at a home in Hamilton Township.
